.To all whom/ lit may concern:

Be it known ,that I, WILLIAM F. GRAY, a citizen of the United States, residing at Millersburg, in the county of Holmes and State of Ohio, have invented a new and useful Churn, of which the following is a specification. v

The invention, relates to improvements in churns.

One object of the present invention is'to improve the construction, of. churns and to provide a simple, inexpensive, and efficientone, capable of being noiselessly. operated at the expenditure of a minimum amount. of power and adapted to effect a rapid production of butter. A further object of the invention is to improve the construction .for mounting the churn-body on the supporting-base and to enable the same to be readily removed therefrom and replaced thereon.

One invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanyingdrawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a churn constructed in accordance with this invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a horizontal sectional view on line 3 3 of Fig. 2. Fig. 4C is a detail perspective view of the standard.

Fig. 5 is a similar view of the detachable arm which supports the upper end of the dashershaft. Fig. 6 is a detail sectional view illustrating the manner of detachably journaling Fig. 7 is a detail sectional view illustrating the manner of yieldingly mounting the master or crank wheel.

Like numerals of reference designate corresponding parts in all the figures of the draw- Ings.

1 designates avertical standard constructed of suitable metal and having a lower forked portion 2, provided with inwardly-extending terminals which are perforated for the reception of suitable fastcningdevices for securing the standards to the base or platform 2. These inwardly-extending terminals or lugs 3 of the forked portion of the standard have curved end edges and form a bearing for an approximately-cylindrical churn body 4,

whichis supported upon the platform or base 2, as clearly illustratedin Figs. 1 and 3 of the accompanying drawings. base is preferably rectangular, the standard being located adjacent to one side thereof, and the opposite side of the lower portion of the churn-body is supported by a block 5, secured to the base or platform at one corner thereof. The upper portion of the standard, which is approximately vertical, as illustrated in Fig. 2 of the accompanying drawings,is provided with a longitudinal slot 6, into which projects a lug 7 of a plate 8, secured by suitable fastening devices to the exterior of the churn-body near the top thereof. The projecting lug is provided with'a threaded socket for the reception of a clampingscrew 9, having an enlarged head which engages the outer face thereof. When the screw -is removed and the dasher-shaft 10 is re leased, as hereinafter described, the churnbody may be readily removed from the base; but when it is arranged thereon it is securely held in place by the clamping-screw 9.

The standard or upright is provided at its upper end with a rigid inwardly-extending horizontal arm 11, .projecting over the adjacent portion of the churn-body and having a removable arm 12 secured to it and forming a support for an adjustable bearing 13 of the upper end of the dasher-shaft. The removable arm is curved upward and laterally, and its lower or outer end is secured to one side of the rigid arm of the standard by a pair of bolts o r screws 14, and the upper end of the removable arm :is provided with a'vertical sleeve 15, inwhich the adjustable bearing 13 is arranged. The upper and lower ends of the .dasher-sh'aft are tapered or conical, and the adjustable bearing 13, which is round, is capable of vertical movement to engage the dasher-shaft'with and disengage it from a tapering or conical socket 16 of its lower end, and it is secured in operative position by The platform or nuts 20, arranged above and below a central hub 21 of a rotary dasher 22, which is provided with radial blades set at an angle, as clearly shown in Fig. 2 of the accompanying drawings. Instead of employing a rotary dasher of the construction shown in Fig. 2 any other form of dasher may be used.

The churn-body is provided with a sectional cover 2i, having a central opening for the passage of the dasher rod or shaft, and the latter carries a frictional pinion 25, located above the lid or cover 24 and meshing or frictionally contacting with a horizontal intermediate friction-wheel 26. The frictionwheel 26, which is mounted on a Vertical stub-shaft 27 of the rigid arm 11 of the standard, is provided with a peripheral groove and receives an elastic rim or ring 28, which insures the proper frictional contact between the wheels and at the same time renders the gearing noiseless. The horizontal frictionwheel engages a vertical master or crank wheel 29 at the inner side thereof adjacent to the periphery of the same, as clearly shown in Fig. 2. The vertical master or crank wheel, which is provided with an eccentricallyarranged handle 30, is mounted on a horizontal stub-shaft 31, projecting outward from the standard 1 at a point below the longitudinal slot and having its outer end 32 threaded for the reception of a nut The threaded end 32 may be reduced, if desired, as illustrated in Fig. 4 of the accompanying drawings, and a coiled spring 34 is interposed between the nut and the outer end of the hub of the vertical wheel to hold the latter yieldingly in engagement with the horizontal friction-wheel. When the vertical frictionwheel 29 is rotated, motion will be communicated through the horizontal friction wheel to\ the dashershaft, and by varying the diameters of the wheels the necessary speed of the dasher shaft may be produced by a comparatively-slow rotation of the vertical gear-wheel. Any suitable means may be provided for retaining the horizontal frictionwheel in the same plane as the friction-pinion 25, if its weight does not produce this resu t.

It will be seen that the churn is exceedingly simple and inexpensive in construction, that it is easily operated, and that it is capable of effecting a rapid production of butter. It will also be apparent that the gearing is readily disconnected by simply raising the vertically-adj ustable bearing 13 out of engagement with the dasher-shaft to permit the churnbody to be removed from the base or platform, when it is released by the clamping-screw. Furthermore, it will be seen that the churn is noiseless in its operation, and that the yielding engagement between the vertical and horizontal wheels, together with the elastic or rubber rim of the horizontal wheel, insures the proper frictional engagement of the gearing.

lVhat is claimed is- 1. In a churn, the combination of a base, a

standard having inwardly-extending lugs secured to the base and provided near its top with a longitudinal slot, a churn-body supported upon the base and fitting against the said lugs, a plate secured to the exterior of the churn-body and provided with a lug having a threaded socket extending into the slot of the standard, a clamping-screw engaging the standard and the threaded socket, and gearing supported by the standard and adapted to operate a dasher, substantially as described.

2. In a churn, the combination of a base, a churn-bod y arranged thereon, a standard secured to the base and having inwardly-extending lugs conforming to the configuration of the churn-body and adapted to support the latter at one side thereof, a block mounted on the base and located at the opposite side, a plate secured to the upper portion of the churn-body, and provided with a lug extending through an opening of the standard and having a threaded socket, a screw mounted in the threaded socket and engaging the standard, a dasher, and gearing supported by the standard and operating the dashcr, substantially as described.

3. In a churn, the combination of a base, a standard rising from the base and provided at its upper end with an inwardly-extending arm, an upwardly-extending arm located at the inner end of the said arm and provided with a bearing, a churn-body arranged on the base and secured at its upper portion to the standard,a dasher-shaft journaled in the bearing of the upwardly-extending arm, a frictionpinion carried by the dasher-shaft, a horizontal friction-wheel mounted on the upper face of the inwardly-extending arm and engaging the pinion, and a vertical gear-wheelarranged on the exterior of the standard and frictionally engaging the horizontal friction-wheel, substantially as described.

4. A churn, comprising a base, a standard rising therefrom and provided with a slot adjacent to its upper end, an arm extending inward and upward from the top of the standard and having an adjustable bearing,a churnbody provided with a projection or lug engaging the slotted portion of the standard, a fastening device detachably securing the projection or lug to the standard, a dasher-shaft journaled at its upper end in the adjustable bearing, a friction-pinion mounted on the dasher-shaft, a vertical friction-Wheel mounted on the standard, and a horizontal frictionwheel arranged at the top of the standard and interposed between and frictionally engaging the pinion and the vertical wheel, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
